Joomla users and extension developers are asked to download and install the packages in order to provide quality assurance for the forthcoming 4.0 and 3.10 releases.
Joomla! 4 is the latest major release of Joomla! CMS. Please note that going from 3.9 to 4.0 is a migration. You would need to upgrade your J3.9 to J3.10, which will be available the day J4.0 is stable. J3.10 has a compatibility checker to help guide you through the migration to J4.0. Please do not upgrade any of your production sites to the release candidate version!
What is this release for?
Joomla 4.0 RC1 is aimed at extension and template developers. To encourage them to work with this release in order to prepare extensions for the stable release of Joomla! CMS 4.0. Users are encouraged to test the package for issues and to report issues in the Joomla! CMS Issue Tracker. Test sites based on this release candidate can be taken through to stable but never use this version on a production site. There will be an upgrade path between release candidates and the final release candidate to the stable of Joomla 4.0 should you wish to try a new site build.
